2. Description of the Related Art A slit type disperser is used for processing operations such as emulsification and dispersion in the field of chemical engineering. As is well known in the art, the slit type disperser is composed of a cage type disperser provided with a plurality of slits in the circumferential direction, and a rotary tooth type impeller rotationally driven in the cage type disperser. There is. The rotary tooth type impeller of the slit type disperser 50 has a processing tank 51 as shown in FIG.
Is connected to the output shaft of an electric motor 53 mounted on the end plate 52 via a drive shaft 54. Therefore, when the electric motor 53 is activated, the rotary tooth type impeller is driven by the drive shaft 54.
The fluid to be processed in the processing tank 51 is driven to rotate at a high speed through the suction tank, is sucked from below the dispersion container, and is sent out from a plurality of circumferential slits, as indicated by the arrow in FIG. .

It is widely used effectively in the chemical field. However, there are some problems to be improved. For example, FIG.
In order to circulate and process the fluid to be treated in the treatment tank 51 as shown in (a) of item (a), the slit type disperser 50 must be located at a relatively lower position in the treatment tank 51. The drive shaft 54 is long. Moreover, since the slit type disperser 50 is simply attached to the tip of the drive shaft 54 and installed and used in the processing tank 51 in a floating state, there is a problem of vibration of the drive shaft 54.

Further, although the slit type disperser 50 has an optimum installation position depending on the property of the fluid to be processed, the processing amount, etc., it is difficult to change and adjust the position because the electric motor 43 is firmly installed. Moreover,
There is an optimum rotation speed of the rotary tooth type impeller due to the physical properties such as the viscosity of the fluid to be treated and the particle size distribution of the particles in the fluid to be treated. A gear mechanism is required, resulting in high cost.

Further, since the electric motor 53 is used just above the processing tank 51 for driving the rotary tooth type impeller, there is a problem that it is not suitable for processing flammable fluid to be processed. Further, even if the capacity of the processing tank 51 is large, there is an inconvenience that a plurality of slit type dispersion machines 50 cannot be simultaneously attached to the drive shaft 54. The present invention is intended to provide a fluid treatment device for emulsification, dispersion, etc. that solves the conventional problems described above, and specifically, there is a problem of vibration of a drive shaft for driving a rotary tooth type impeller. , The installation position and the drive speed of the rotary tooth type impeller can be easily changed, and it can be applied to the treatment of flammable fluids.
